Any diagnosis of the power top system should begin with the use of a scan tool and the proper Diagnostic Procedures Information. The scan tool can provide confirmation that the Programmable Communications Interface (PCI) data bus is functional, that all of the electronic modules are sending and receiving the proper messages on the PCI data bus, an

d that the power top motor is being sent the proper hard wired output by the Body Control Module (BCM). Place a 12-volt test light between the fused B+ and power top UP relay control terminals in the harness side of the connector. With the ignition switch in the RUN position, operate the power top switch in the UP direction. The test light should light. Place a 12-volt test light between the fused B+ and power top DOWN relay control terminals in the harness side of the connector. With the ignition switch in the RUN position operate the power top switch in the DOWN direction. The test light should light. Turn the ignition switch to the OFF position. Disconnect the BCM. Using an ohmmeter, check for continuity on the power top UP and DOWN circuits between the BCM and the power top relay assembly. Continuity should be present. The power top system allows the convertible top to be raised and lowered electrically by actuating a switch in the center floor console. The power top system receives battery feed through a fuse in the Power Distribution Center (PDC) when the ignition switch is in the ON position. The power top motor is part of the motor/hydraulic pump assembly and cannot be serviced separately. If the motor is inoperative, the complete assembly must be replaced. The power top switch is hard wired to the Body Control Module (BCM) through the Power Top Switch Mux circuit. The BCM supplies a multiplexed voltage of...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
